Surgery to remove a chondrosarcoma from the C2 vertebra. The endoscope was advanced along the narrow passage from the mouth to the pharynx. A vertical midline linear incision along the posterior part of the pharynx with monopolar electrocautery was followed by an incision in and a lateral retraction of the longus colli muscles. The tumor was pearl-colored and solid and was removed via en-bloc resection using endoscopic curettes, punches, and a high-speed drill. Following the resection, the muscle and mucosa were sutured with 3.0 vicryl.

Compressing this irregular mixed echogenic fluid collection with the ultrasound probe produces the swirl sign, which represents purulent material swirling under pressure. However, the exact nature of the fluid cannot be determined by ultrasound alone.
